Bayberry (Myrica spp.)
While some complementary and alternative techniques have been studied scientifically, high-quality data regarding safety, effectiveness, and mechanism of action are limited or controversial for most therapies. Whenever possible, it is recommended that practitioners be licensed by a recognized professional organization that adheres to clearly published standards. In addition, before starting a new technique or engaging a practitioner, it is recommended that patients speak with their primary healthcare provider(s). Potential benefits, risks (including financial costs), and alternatives should be carefully considered. The below monograph is designed to provide historical background and an overview of clinically-oriented research, and neither advocates for or against the use of a particular therapy.

  • Note: Due to the lack of primary research and the extensive and often interchangeable use of different varieties of bayberry, this monograph addresses the available data on a number of commonly used species of the genus Myrica.


  • Myrica is a genus of about 35-50 species of small trees and shrubs in the family Myricaceae, order Fagales, found throughout most of the world. Occasionally, the genus is divided into two genera, Myrica and Morella, with the former restricted to only a few species and the remainder appearing under Morella. Common names include bayberry, bay-rum tree, bog-myrtle, candleberry, sweet gale, and wax-myrtle.
  • Several species of Myrica have been used in folk medicine in Asian, Native American, European, and African cultures. According to Daniel Moerman's Medicinal plants of Native America, the branches of sweet gale (Myrica gale) were used by the Bella Coola Indians of British Columbia to prepare decoctions for use as a diuretic or as a treatment for gonorrhea. Other Native American peoples have used bayberry for dysentery, diarrhea, fevers, gynecological conditions, bleeding in the uterus, and as a toothache remedy. Myrica cordifolia, native to South Africa, has been traditionally used as an astringent, food source, and for tanning hides. Another species indigneous to Africa, Myrica quercifolia, has also been prescribed by native herbalists to cure stomachaches.
  • The early American colonists did not initially use the herb medicinally, but rather made candles, soaps and cosmetics from the bayberry fruit.
  • Today, bayberry remains popular in Asian herbalist traditions. In Taiwan, bayberry is often recommended for stomach disorders and diarrhea, and in China, it is used as an astringent and pain reliever.
